A group of plant cells was exposed to radiation, which damaged the chloroplasts and caused them to lose function. If the mitocho

ndria were unharmed, what would happen to the overall function of the plant cells?
A.
The cells would not be able to release energy from biomolecules, but would be able to make food.
B.
The cells would not be able to break down waste, but would be able to replicate DNA.
C.
The cells would not be able to replicate DNA, but would be able to break down waste.
D.
The cells would not be able to make food, but would be able to release energy from biomolecules.

Answer: Option D, The cells would not be able to make food, but would be able to release energy from biomolecules.

Explanation: We should first understand roles of these two organelles in plant cell. Chloroplast- its function is to absorb sun's energy and convert the CO2 into glucose. Mitochondria- It makes energy from glucose and other molecules present in plant cell.

So, its obvious if chloroplast is not working, food will not be formed. That's why option A is incorrect. Again, functions mentioned in Option B are also incorrect, as DNA replication takes place inside the nucleus, and waste is broken down by lysosomes. Same is the reason with Option C, so its wrong option. Only Option D describes the functions correctly.
